MOLD FOR BRICK OR ARTIFICIAL STONE.

SPECIFICATION forming part of Letters Patent N. 679,232, dated. July 23,1901. Application iiled December l0, 1900. Serial No. 39,263. (Nomodel.)

To @ZZ whom it may concern:

Be it known that I, SoLoMAN M. KIMBLE, a citizen of the United States,residing at Corunna, in the county of Shiawassee, State of Michigan,have invented certain new and useful Improvements in Molds for Brick orArtificial Stone; and I do declare the following to bea full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the igures of referencemarked thereon, which form a part of this specification.

This invention relates to a machine for making brick or artificialstone; and it consists in the construction hereinafter fully set forth,and pointed out particularly in the claims.

The object of the invention is to provide simple and efficient means forforming and pressing brick made of sand and cement or other materials insuch manner as to render the brick firm and compact and allow them to beremoved from the press without injury, the arrangement being such as toenable the bricks to be rapidly and cheaply made.

The above object is attained by the device illustrated in theaccompanying drawings, in which- Figure 1 is a central vertical sectionthrough the brick-forming press or mold and the base upon which it ismounted. Fig. 2 is a plan view of the mold in which the bricks areformed, showing by dotted lines the movement of thehorizontally-retractable dividingplates, which are adapted to separatethe mold into a series of divisions adapted to contain the bricks. Fig.3 is a transverse section showing the position of parts when thematerial is confined within the mold and the dividing slides orpartitions are withdrawn to separate the material into a series ofindependent bricks. Fig. 4 is an elevation of the bricks upon thedrying-board after being molded in the press. Fig. 5 is a longitudinalsection through the press, showing the material therein separated intobricks by the dividing-plates. Fig. 6 is a central vertical sectionthrough the mold or press with the hopper in position thereon. Fig. 7 isa vertical transverse section through the mold, showing the bottomremoved and the clamp of the mold released. Fig. S is a perspective viewof the follow -board and ends of the mold or press.

The base comprises the upright parallel sides 1 and 2, united at theirlower ends by the base-piece 3. Interposed between said sides near theirupper end is a blockt, which is rigidly attached to the side 1 and isthereby maintained in position. Said block forms the bottom of the moldin which the bricks are formed- The sides of the mold are formed by theupper ends 5 and 6, respectively, of the sides 1 and 2, which continueabove said block. The ends of the mold are formed by the end pieces 7 ofthe follow-board 8, which is adapted to lie upon the block 4c betweenthe sides of the mold and support said end pieces, so as to close theends of the mold, as clearly shown in Figs. 1, 5, and 6. The side 2,whose upper end 6 forms one of the sides of the mold, is free from theblock 4., as will be seen upon referring to Fig. 7. Passing transverselythrough said block are the rods 9, whose outer ends pass freely throughthe Y side 2 and are provided with a hooked portion 10. The hooked endsof said rods lie in eccentric ways 11, formed circumferentially in theannular bar 12, which crosses the face of the side 2 and lies contiguousthereto, being supported in position by the hooked ends of the rods 9.Projecting from the bar 12 is an operative handle or lever 13, by meansof which said bar may be rotated. When said bar is turned so that thehooks 10 lie in the eccentric ways 11 thereof, the side 2 is releasedand allowed to spring outward, as

shown in Fig. 7. By throwing the handle downward so as to rotate saidbar to cause the hooks l0 to ride out of said ways, said bar is carriedforcibly against the side 2, whereby said bar is clamped against the endof the block 4 and held rigidly in position, as shown in Fig. 3.

A cross-piece 14 is mounted to slide horizontally upon theysupporting-rods 15, which are secured in the block 4 and projectlaterally from the side 1, their outer ends being turned upwardly, asshown at- 1G, to arrest said cross-piece in its outward movement.

Attached to said -mcvablecross-piece is a series o'fhorizontallyextending approxin'iately parallel dividing blades orpatitions 17,l which pass through openings in the side 5 of the mold andextend transverselyacross the'ch'am-v ber of the mold, their rear endsentering slots 18 in the side 6, whereby said dividing-blades are heldfirmly in position when shoved into, place across the chamber of themold andy serve to divide said mold-chamberinto a Se'- ries of parallelspaces 19, in which the bricksM are formed, as indicated at 20. After`forming thebricks the crosspiece 14 is drawn outwardly upon thesupporting-rods `15, s'o 'as -to withdraw the dividing blades orpartitions from the bricks in `the mold, 'whereby the 'bricks areseparated in a manner -toenable them to be discharged therefrom `and,placed yfordrying without contact,-asjhereinafter exrplained.

A rectangular hopper 21 'is Aadapted'to be Said 'hopper adapted tobe's'crewed against the Iends 7 Yto n'raintain the hopper securely inposition.

lin the operation of this device the followyboard 8, which forms thebottom-of `the mold, isfirst placed upon the base-block4 between thesides 5'a'nd 6, vso that Vthe'ends '7., carried 'bysaid board, willclose the 'mold and form Ythe end pieces thereof.

The lever 13-is then thrown downward, so as to clamp the side 6 of themold in place, vand the cross-.piece 14 -is Lmoved upto the side 5 tocause'the dividing-plates to `extend across the mold and divide itintobrick-forming spaces. The `hop'- Vper isthen placed in position a-nd thesand and cement i-n proper proportion or other ma- -terials from whichthe-bricks are to be'formed are placedin the Vhopper so as to fill thespace in the mold between the dividing-blades 17. The materia-ls -arethen tamped down into said dividing-spaces, so asto com-pact saidmaterials-between saidpa-rtit-ions, after which Vthe hopper isremoveda'ndthe materials made smooth and level with the top of the mold.A drying-board 24 is then placed -upon vthe top Yof the mold and securedby the hooks v25,

which are `hinged at 26 to the ends 7. These hooks engage the oppositeends of the drying-board in a manner to maintain it `firmly in vplaceupon the top of the mold. The dil viding-plates are then withdrawn Vfrombetween the bricks in the' mold by drawing ontward the cross-piece 14.The bricks are then released from pressure by throwing upward v thelever 13, thereby unclamping the side 6,

materials are placed therein. 'the size-of vthe mold artificial stone ofany when the-follow-board, withthebricks thereo'n, `maybe lifted fromthe mold. After removing the bricks from the mold they areV turned over,so as to rest upon the dryingboard 24, as shown in Fig. 4. Thefollowboard is then removed by disengaging the 'hooks 25, therebyleaving the bricks 2O per- Afe'ct'and intact upon the drying-board todry. After the formed bricks have been deposited upon the drying-boardthe followboard is again placed in the mold and the operation repeated.In this manner brick or artificial stonemay be formed of sand andcement, which when 'dry are superior for building purposes and may bevery quickly and cheaply made. After the mixture from which the bricksare formed has been tamped firmly yinto the divisions of 'the 'molds the,pressure 'uponthe dividing-plates renders it difficult to sta-rt 'thecross-piece '14 when Adesiring to withdrawithe plates from the mold. Toenable "said cross-piece to be moved easily atthe start, levers 27 arepivotedo'r hinged at 2S-to't'he mold so that their short ends extend`inwardlybetween the sideof the mold Iand the cross-piece 14, in which`position a 'movement of lthe outer endofsaid levers toyward the -endsof theA mold will force said cross-piece outwa-rdlyanddraw upon vthedividing-blades 17, as will be readily Iunder- If desi-red,'anartificial stone the entire size ofthe -mold may befo'rmed by leavingthe dividing-,platesout ofthe mold-space whenthe B'ychang'ing desiredvsize ymay be made.
